摘要：The security mechanisms such as authentication and confidentiality is highly challenging in a contentbasedpublish/subscribe system and due to the loose coupling of publishers and subscribers, authentication andconfidentiality of publishers and subscribers is difficult to achieve. In particular content-based approaches in brokerlessenvironments do not address confidentiality at all. This paper presents to provide confidentiality and authenticationin a broker-less content-based publish-subscribe system. The authentication and confidentiality and other securityapproach of publishers and subscribers ensured, by adapting the certificate based encryption mechanism. In certificatebased encryption signature not only acts as certificate but also as encrypt and decrypt key. To encrypt or to decrypt amessage, a key holder needs both its public key and private key and an up-to-date certificate from an authorizer.Certificate-based encryption combines the best aspects of identity-based encryption and public key encryption. Thismechanism describes how certificate-based encryption can be used to construct an efficient PKI requiring fewerinfrastructures than any previous method.
